Sliding door device for vehicle

摘要

A sliding door device for a vehicle is disclosed. The sliding door device for a vehicle includes a sliding door installed in a vehicle body to be slidingly moved to open and close a door opening formed in the vehicle body. A vehicle body weather strip is attached to the door opening. A sensing device is installed in the vehicle body weather strip to sense that an object or an occupant is jammed in a state where the sliding door is closed. An electronic control unit (ECU) for receives a sensing signal of the sensing device to control opening and closing of the sliding door. Therefore, it is possible to effectively prevent an object or an occupant from being jammed in a process of closing the sliding door.

主权项

1. A sliding door device for a vehicle, comprising:
a sliding door installed in a vehicle body to be slidingly moved to open and close a door opening formed in the vehicle body; a vehicle body weather strip attached to the door opening; a sensing device installed in the vehicle body weather strip to sense that an object or an occupant is jammed in a state before the sliding door is completely closed when the sliding door is closing, wherein the sensing device comprises:
a door opening and closing sensor for sensing opening or closing of the sliding door; anda jam sensor for sensing that the object or the occupant is jammed in a state where the sliding door is closed; an electronic control unit (ECU) for receiving a sensing signal of the sensing device to control opening and closing of the sliding door, wherein the sliding door comprises a door weather strip attached to the vehicle body weather strip to seal the door opening, and wherein the door opening and closing sensor comprises:
an elastic contact protrusion pressed by the door weather strip in a state where the sliding door is closed and restored to an original shape when the elastic contact protrusion is separated from the sliding door;a sensing rod integrated with the elastic contact protrusion to be elongated and contracted in line with elongation and contraction of the elastic contact protrusion;an opening and closing sensing terminal fixedly mounted at one leading end of the sensing rod and connected to the ECU; anda spring inserted into an external circumference of the sensing rod to elastically support the sensing rod.
